Getting an error when running ArchLinux

[EpicBox]

Not sure if this is the right place to post it or not, if not I (or a mod(?)) will try to move it.

Anyways, when trying to run my ArchLinux 32bit VM I get this error:

Failed to open a session for the virtual machine <NAME>.

Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

I'm running Windows 8.1 64 Bit AMD Phenon(tm) 9500 Quad-Core Processor
(Not sure if my processor is of any useful information or not, but better safe than sorry)

It looks like you have an unsigned DLL that is stopping VirtualBox due to security hardening. If you know what this is associated with you could un-install the program and see if it allows VirtualBox to run properly. Other than that you would need to post in the specific area just for this kind of issue https://forums.virtualbox.org/viewtopic.php?f=6&t=64111

uxtheme.dll is a DLL used for Windows themes, which many people hack in order to get free Win7 like themes to run on Win8 (and on XP!). I'm using a hacked theme DLL myself on XP right now. Of course hacking the DLL invalidates the certificate.

I sympathise with the OP. I hate that thrice damned Win3-alike look in Win8. In fact at least Win3 had dithering to add texture.

I think I'll add a note to the 4.3.18 hardening discussion about this.

You can issue a certificate yourself (it doesn't need to be validated by a higher authority), add it to the Trusted Root Certification Authorities and to the Trusted Publishers lists (in certmgr.msc). Then sign your hacked dll with that certificate, using the signtool tool (from the Windows SDK or WDK):

signtool sign /v /ph /f MyCertificate.pfx  /t http://timestamp.verisign.com/scripts/timestamp.dll dllname.dll

Thanks for the tip.

Actually, I forgot something very important. The dll must also have the INTEGRITYCHECK flag present in the PE header. I'm not sure if you can just hack the header. But I successfully build and run the hardened VirtualBox OSE (64 bit), which required me to also build signed dlls for openssl and Qt.
